My 99 has the wobble also. It's real noticable at around 50-60 mph. I've heard it is normal in the Cherokee. I've had it to two dealerships and can not find the problem. I've replace the wheel bearings, rotors, steering stabilizer bar, ball joints, u-joints, drive shaft and four brand new tires. Along with having the wheels balanced with two different sets of new tires mounted and put on for a test drive. They even exchanged axles with another Jeep. What's up with the certified Jeep mechanics not being able to determine what it is or Chrysler for that matter. I only have 155k miles on it. Maybe I need a lift also, what's the cost?
